Biodiversity of methanogenic and other Archaea in permanently frozen Lake Fryxell, Antarctica. Appl Environ Microbiol 72
Antarctica. Two clusters of methanogens were detected in the sediments, and another cluster of possibly methanotrophic Euryarchaeota was detected in the anoxic water column just above the sediments. One crenarchaeote was detected in water just below the oxycline. The Archaea present in Lake Fryxell...
